Lab Use for Pharmacy & Sample Grinding 120mm Glass Mortar and Pestle

For achieving the finest, most uniform powder, glass is superior due to its perfectly smooth surface that provides precise particle control. Porcelain has a slightly textured surface and is better for general grinding tasks where extreme durability against impact is needed. Choose Glass For: Ultra-fine grinding & uniform particle size/Pharmaceutical compounding/Sensitive analytical samples. Choose Porcelain For: General-purpose grinding of harder materials/High durability against chipping/Cost

While the core glass mortar and pestle purpose is for solids, it can be used for a glass mortar mix that includes small amounts of liquid to form pastes (levigation). Avoid using large volumes of liquid.

For effective glass mortar and pestle use, place the solid in the glass mortar, apply firm, circular pressure with the pestle, and use the frosted surface to your advantage. Start with coarse grinding before moving to a finer powder for best results.

Rinse immediately after use. For stubborn residues, use a brush with a appropriate laboratory detergent. Avoid abrasive scouring pads that could damage the frosted texture. The glass is generally acid-resistant for chemical cleaning if needed.
